Phosphorus (P) is a critical macronutrient for all living cells, as it provides the phosphate-
ester backbone of nucleic acids, plays a crucial role in the transmission of chemical energy …

The main controlling factors of organic matter accumulation in the Upper Ordovician Wufeng–
Lower Silurian Longmaxi Formations are complex and remain highly controversial. This …

The geochemistry and mineralogy of organic-rich sediments of the Rietheim succession in
northern Switzerland were studied to evaluate the main impacts of the early Toarcian …

The purpose of this study was to quantify phosphorus bioavailability and various forms of
this element in surface sediments of the southern Caspian Sea. To do, sediment samples …

Iron is known to stimulate surface ocean productivity, as well as intervene with bacterially-
mediated processes of organic matter remineralization, during early diagenesis. In this …

Surface and core sediments were collected off the eastern coast of Hainan Island (South
China Sea), and a sequential extraction method (SEDEX) was used to separate and quantify …

Phosphorus (P) as an essential macronutrient, plays a crucial role in the regulation of
biological productivity and biogeochemical cycling of other biogenic elements in aquatic …

The organic-rich lower Silurian Longmaxi Formation is now regarded as the favorable target
for shale gas exploration and production. However, the mechanism of organic matter …

The distribution of different forms of phosphorus in surface sediment from 17 sites were
investigated by SEDEX method. The sites were divided into three sectors: Santos Channel …

The late Ediacaran witnessed an increase in metazoan diversity and ecological complexity,
marking the inception of the Cambrian Explosion. To constrain the drivers of this …
